Can Genital Herpes Lesions Show Up On The Penis Head With No Prior Symptoms?

1) can genital herpes lesions show up on the penis head with no prior symptoms?. i had 3 lesions on my penis that were very red but they appeared all of a sudden. I felt a strong burning sensation 2 days after them appearing. is this usual for lesions to appear and the burning sensation to start after in a primary outbreak? 2) How fast can valovocyvir heal a primary outbreak? i had lesions for 3 days before going to the doctor and i took medication the following 2 days which would total 5 days for the whole episode to be over. the lesions dissapeared completely in a total of 5 days from start to finish. They were very fluorid and dissappeared very fast. Is this usual or can it mean that i had something else since ive heard it takes longer for a primary outbreak to heal from start to finish than just 5 days especially if symptoms are fluorid. I had what looked like blisters on one of the lesions but they never burts, scabbed, or ulcerated. I was prescribed valovyclocir 2 pills of 500mg every 12 hours for 10 days but i only took them 2 days since the lesions completely dissapeared. Some doctors have told me that it could be that the medication worked and some say that valoviclocir would take at least 4-7 days to heal lesions so i am confused.
